My understanding is that payment processors find themselves enforcing the Overton Window lest they run afoul of present legal trends. There's a sliding scale on what is or is not acceptable for them to be facilitating and it changes constantly.

Within sex work, where on the sliding scale of acceptability does enabling a "self employed cam model", vs facilitating a "trafficked cam model" fall, especially when a payment processor has no idea what is going on behind the scenes? Is the payment processor supposed to watch the stream and recognize a gang tattoo and conclude that one is trafficked while another is not?

I can see people on the political right in the US saying they shouldn't process payments for pornography at all, and people on the left saying "I can't believe that <company> facilitates trafficking or victimization". I'd see the payments processors saying "It's not worth it to process any payments for any pornography at all".
